PROBLEM TO BE SOLVED: To improve operation efficiency. SOLUTION: An axial gap motor is structured with a rotor which can rotate around a rotating shaft and stators which are arranged to face the rotor from both sides in the direction of the axis rotation parallel to the axis of rotation of the rotor. The rotor is structured with a plurality of main permanent magnet pieces 41 whose magnetized direction is in the direction of the axis of rotation and which are arranged in the circumferential direction, a plurality of sub-permanent magnet pieces 43 whose magnetized direction intersects at right angles the direction of the axis of rotation and which are arranged near the end of the main permanent magnet pieces 41, and magnetic material members 42 arranged on one side and the other side in the direction of the axis of rotation of the main permanent magnet pieces 41 between the two sub-permanent magnet pieces 43, 43 adjacent in the circumferential direction. The magnetic material members 42 is made of a rolled material formed by the rolling processing. The rolling direction in the region inside the radial direction or outside the radial direction is made to correspond to the direction of the axis of rotation, while the rolling direction in the region between the inside the radial direction and outside the radial direction is made to correspond to the circumferential direction of the rotor.
